Angle m has a measure between 0 and 360 and is coterminal with a –620° angle. what is the measure of angle m?
100°
110°
120°
130°

Two angles are said to be coterminal if when they are drawn in a standard position, their terminal sides are on the same location. A coterminal angle can be determined by adding or subtracting 360 degrees to the given angle. Thus, for the given -620 degrees angle we add continuously 360 until we find an angle that is in the choices.

-620 + 360 = -260-260 + 360 = 100

Therefore, Angle M is equal to 100 degrees.
